Hello Kienan, thanks for the reply. For my analysis, I am also looking
for these tracepoints:
- vmsync_gh_guest
- vmsync_hg_guest
- vmsync_gh_host
- vmsync_hg_host
does the canonical upstream version have them ? thanks.
No, it doesn't. Those tracepoints are custom by the looks of it, and not
tracepoints that exist in the mainline linux kernel.
thanks,

Hi François,
We don't support the forked version of LTTng modules that you are using
(https://github.com/tahini/lttng-modules
<https://github.com/tahini/lttng-modules>)
The canonical upstream version available at
https://github.com/lttng/lttng-modules
<https://github.com/lttng/lttng-modules> has tracepoints such as
kvm_entry
and kvm_exit.
E.g.
https://github.com/lttng/lttng-modules/blob/06a1fc639b10b40c0ffc412f3fb663632e42dae6/include/instrumentation/events/arch/x86/kvm/trace.h#L20

thanks,

(kmv_entry, kmv_exit) for my analysis. I added the "addons" folder from the "addons_vm" branch of this repository:
https://github.com/tahini/lttng-modules <https://github.com/tahini/lttng-modules> <https://github.com/tahini/lttng-modules
<https://github.com/tahini/lttng-modules>> to the current version of lttng-module github repository. However, I am
encountering these errors when compiling
